Four patients are described in whom a follicular carcinoma developed following thyroidectomy for a benign follicular neoplasm. It is possible that the initial thyroid neoplasm was a well- differentiated follicular carcinoma which was microscopically indistinguishable from a benign adenoma. Realizing this pathologic pitfall in thyroid diagnosis, the need for meticulous examination of the pa...

In the present study, 7 patients with brain hemorrhage combined with intracranial tumor were investigated for about 3 years. Furthermore, the previous reports related with such cases were also reviewed. In all of these patients, hemorrhage was a main characteristic of the diagnosed neoplasm. The clinical data were identified by computed tomography (CT) scanning in the present study. CT scanning...

INTRODUCTION Histiocytic sarcoma is a rare neoplasm with few cases reported in the literature of which some were diagnosed in animals. This neoplasm arises from abnormal reticuloendothelial system cell proliferation of histiocytes and has an aggressive behavior especially if located in the central nervous system. We present the first case of a patient with histiocytic sarcoma that involved the ...

Even though nearly thirty-years of clinical research has attempted to improve the outcomes for patients with central nervous system neoplasms, the survival remains limited for a majority of these patients. Diverse intracellular signaling pathways involving apoptosis, invasion, angiogenesis and relevant mechanisms of resistance associated with CNS neoplasms are continuing to be elucidated. Phase...

Within a cohort of 1,915 consecutive patients with myeloproliferative neoplasm followed for a median time of 5.2 years (range 0-33.3), we investigated the occurrence of lymphoid neoplasm with the aim of defining this risk and to investigate the role of genetic predisposing factors. We identified 22 patients with myeloproliferative neoplasm who developed lymphoid neoplasm over their lifetime. We...
